Stephen Collins, who starred on the WB series “7th Heaven,” resigned Tuesday from the national board of SAG-AFTRA following a New York police investigation into sexual abuse allegations, an insider at the union confirmed to TheWrap.

The actor was elected to a three-year term in August 2013, and is a long-time SAG-AFTRA member.

Collins made the alleged confession during a 2012 therapy session with his estranged wife Faye Grant, who is believed to have secretly recorded the conversation. Secret recordings are legal in the state of California if done in the name of gathering evidence against a person who has committed a violent felony.

The famous TV dad on Tuesday was also fired from “Ted 2,” the upcoming sequel to Seth MacFarlane‘s raunchy 2012 teddy bear comedy.
